recent update to 11.2.6 on iphone 5s won't stay connected to wifi
I recently updated the software on my iphone 5s to iOS 11.2.6 and now it won't stay connected to my wifi at home. It asks me which "which wireless network?" with every activity, several times a minute. I have tried clicking "renew lease" but it does not change. It also constantly disconnects from the wifi. My macbook is at the far end of the house from our router and has no problem.
iPhone 5s, iOS 11.2.6
